This invention relates to bells, and particuarly to ringing mechanismsfor locomotive bells of'the type adapted to be rung either by motor ormanually operable striking means.

5 The object of'the invention is to provide a stationary bell with aclapper having motor and manual actuating means adapted to be operatedindependently of each other, which construction will comprise asimplified mech- 1'0 anism, of low initial cost, and which will beinexpensive to maintain. I

Additional advantages of the construction will be apparent from thefollowing detailed description thereof, taken in connection'with theaccompanying drawings, in which:

Figure 1 is a side elevation, partly in section, of a bell and supportwith the invention applied thereto and Fig. 2 is a rear'view of Fi .1. IY

in the practice of the invention'referring descriptively to the specificembodiment thereof, which is herein exemplified, the stand 1, comprisesa base 2, which is adapted to be 2 bolted or otherwise secured to theshell of a locomotive boiler or any other desired base, and a U'shapedupwardly and inwardly extending supporting arm 3. A bell 4, of thestandard type, is provided with a hollow frusto-conical extension 5, atits top, which fits within 'a socket 6, formed at the upper end ofthe-supporting arm '3.

Disposed inthe upper interior of the bell 4, is a motor 7, comprising acylinder 8, and a fluid pressure actuated piston 9; an inlet port 10,being formed at the end of the cylinder, and an outlet port 11, beingformed in the'same, inwardly spaced from the inlet port. The piston 9 isprovided with a stem 27 which extends rearwardly thereof within thecylinder. c In the lower part of the cylinder a slot 28 isiformed and acorresponding slotv 29 is formed in the bottom of the piston 27 over theslot 28. It will be understood that the specific construction ofthemotor is nota motor may be locatedin'the aforesaid'po'sition. Theparts comprising the motor have therefore been illustrateddiagrammatically and the relative positions of the valves and part ofthis invention, but that any suitable piston will, ofcourse, be adjustedin the con-V ventional manner, well known in theart to producewthedesirediresults. A hollowstem 12,is secured in the upper side of thecylinder, and passes through theextension. 5, .on the bell, its upperend projecting-beyond the socket 6, andbeing threadedto receive a'nutr13, which is screwed thereon over a washer l4, and therebyrigidlysecures the motor and bell in position on the arm 3. A passageway 15,is'formed in'the cylinder 8, connecting the inlet port '10,"with theinterior of. thehollow stem 12,and the upper end-of the stem; is connected to apipe 17, by means 'ofthe'lconnection 16,fitted'at the endofthe same the pipe 17 leading to a source of fluid pressure and'a controlvalve forthe same (not shown), -,--'Ihe bell clapper 18, is.piv'otallypo'nnected to'the lower part of the cylinder-7, by thepin 19.Theupper end of the clapper,-abojvethe pin, isprovidedwith 'a tonguev20, which extends into the cylinder through the-slot 28 apd' is looselyheld in the slot 29 of the piston WhBHitilS desired to operate thevbell'by the motor, fluid pressure is applied through" pipe 17,.thehollow, stem 12, the passageway 15,; and theinlet port 10, to the end ofthe piston 9, withincthe cylinder 8, forcing the piston and :itsstemloutward; carrying back the tongue 20, and therebyactuating" theclapper 18. When, the piston passes the outlet {port 11;, however, thefluid pressure is thereby placed in communication with the atmosphere,and the pressure on the piston is relieved. Upon the return, strokeyoftheclapper, its tongue, 20,,will throw the'piston back tfo its initialposition, and the fluid pressure will thereupon again, force the: sameforward, the clapper continuing to be thus actuated as longasfthefluid'pressure' is apoperably disposed within-the said: hearing.

An upwardly extendingarm 23, is '.-rigidly secured to the inner endofthe shaft 22, by means of a squaredxfittingon the'shaft and arm, andata'per pin (not shown), thefupper end: of the arm being turnedinwardlyarid encircling the bell clapper 18,- soas'to leave clearancespace around same when in neutral position. At the outer end of theshaft 22, an arm 25 is similarly secured as indicated at 24. The arm 25extends upwardly on the .outside'oii the bell 4. The shaft 22, and thearms 23 and 25, thus comprise a two farm lever, with the shaft as theircommon fulcrum, the arms movinginunison so that the clapper 18, will beactuated by the end of the arm 23 uponmovement of the arm 25. The upperend oi the M11125 is provided with a button 26 to which a rope or other,

' tion, the trunnions necessary in a revolving bell structure areeliminated, as well as the flexible joints forthe actuating fluid con-Jduits usually employed ,in similar motor mechanisms. The shaft 22 willrequire very little pull in order to move the bell clapper.

when ringing by hand,"an'd there will be practically no wear on thesame. In'this construction therefore, there will be practically nomaintenance involved except in them'otor mechanism." This being entirelywithin the bell is guarded fromthe elements, and consistingof butone-moving part is of the-sturdiest and most durable construction..Itwill be further noted that the'pip'e, hollow stem, and passagewayare-so located as to provide the simplest possible "fluid pressureconduit with a minimum number of joints and conhections. I l V, IWhilether'e has been described herein'f a preferred specific embodimentof the invenuse, it will be understood that there are many "andvar-i'ous changes and modifications in the details 'of :"constr1rctionwhich may prove desirable, and will be apparent tothose skilled the arhand that all and any such changes and modifications are contemplated 3 sap'art of this invention with-inthe sc'ope oftheappended cla'i ms.
